Trophy equals 15 that's the answer
Get into form (x-h)^2=4p(y-k)
vetex is (h,k)
so
1/2(x-7)^2=y+4
times 2 both sides
(x-7)^2=2(y+4)
(x-7)^2=4(1/2)(y-(-4))
vertex is (7,-4)
Just think of slope as the rate of change
Answer:
X=5 the angle is 76 degrees
Step-by-step explanation:
The bottom angles are corresponding. So 52+52=104, so you need 76 more degrees. Then simple math to caculate x.
